Frequently Asked Questions
What is the 4-point GPA scale?
The 4-point GPA scale (4.0 scale) is the standard grading system used by US universities. Grades range from 0.0 (F) to 4.0 (A). Letter grades map to GPA points: A=4.0, B=3.0, C=2.0, D=1.0, F=0.0. Plus and minus variants (A-, B+) use increments of 0.3.
How do I calculate my 4.0 GPA?
Multiply each course's GPA value by its credit hours, sum those products, then divide by total credit hours. Formula: GPA = Σ(Grade Points × Credits) / Σ Credits. A 3-credit A and 4-credit B gives: (4.0×3 + 3.0×4) / 7 = (12+12)/7 = 3.43.
Is 3.0 GPA good on a 4.0 scale?
Yes, a 3.0 GPA is generally considered a 'B' average and meets minimum requirements for many graduate programs and employers. For competitive programs, a 3.5+ is preferred. Honors programs typically require 3.5 or higher.
How does the 4-point scale compare to international grading systems?
The US 4.0 scale is unique to North America. Other countries use different scales: UK uses First/2:1/2:2/Third, Germany uses 1-5 (inverted, lower is better), India uses 10-point CGPA or percentage, and France uses 0-20. GradeAtlas converts all these to the 4.0 scale.
